Would it be creepy to add her on Facebook?

There's this girl that I used to work with. girl and I stare into each others eyes for way more than usual time and no one says anything. The job has my location in the store because we deliver food and once walked into the room and I saw her looking at the screen because it goes off when someone returns and she turned around and looked directly at me and stared for longer than usual. Another time she asked me for help to carry something to her car. Would it be creepy to add her on Facebook?
